Objective To evaluate the parenteral complications and their risk factors and to study the immune status by detecting immunoglobulin and lymphocyte subsets in children with rotavirus enteritis. Methods Sixty-four children with rotavirus enteritis who were treated in Shengjing Hospital of China Medical University between January 2007 and December 2008(observation group) and 18 healthy chiIdren for health screening at pediatric health care center (normal control group) were reeruimd.Clinical manifestations were collected,stool specimens were detected for rotavirus using ELISA,lymphocyte subsets were detected using flow cytometer,and immunoglobulin.liver enzyme and myocardial enzyme were detected.Results Rotavirus enteritis may be complicated by parenteral complications(liver,myocardium,respiratory and nervous system).The activity of ALT,AST,LDH,CK and CK-mB were higher in observation group than that in normal control group(P<0.05).In observation group,liver injury rate in children younger than 12 months was higher than that in children older than 12 months,and the activity of CK and CK-mB were highcr in severe diarrhea cases[CK(324.5±995.5)U／dl,CK-mB(93.8 4±61.5)U／dl]than that in mild diarrhea cases [CK(252.8±130.4)U／dl,CK.mB(59.6±32.6)U／dl](P<0.05).The level of IgG was lower in observation group[(4.46±1.56)g／L]than that in control group[(5.80±1.67)g／L](P<0.05).Lymphocytes subsets study revealed that the activity of CD4+ in observation group[(29.0±4.18)％]was lower than that in control group[(38.6±3.97)％](P<0.05),the activity of CDl9+ [(38.8±3.94)％]was higher than that in control group[(23.1±7.70)％](P<0.05)and the CD4+／CD8+ ratio was reverse in observafion group.Conclusion Rotavirus enteritis may be complicated by parenteral injuries which get liver,myocardium,respiratory and nervous system involved.Children with rotavirus enteritis Call lead to low immune function.Determination of liver enzyme,myocardial enzyme,immunoglobulin and lymphocyte subsets has important clinical significance to monitoring the change of condition and guiding treatment.

Objective To investigate the expression of Skp2 and Cx43 in cervical carcinoma and to study their relationships and clinical significance. Methods The expression of Skp2 and Cx43 was examined by immunohistochemical method in 48 cases of cervical carcinoma tissue, 84 cases of cervical intraepithelial neoplasia (CINⅠ - Ⅱ 45 cases, CINⅢ 39 cases), 28 cases of chronic cervicitis. Results Skp2 expression in cervical carcinoma was higher than that in the CINⅠ - Ⅱ and chronic cervicitis (P <0.05), Cx43 expression was lower in cervical carcinoma than that in the CINⅢ, CINⅠ - Ⅱ and chronic cervicitis (P <0.05). The expression of Skp2 was correlated with histological differentiation and lymph node metastasis (P <0.05). The expression of Cx43 was correlated with the lymph node metastasis (P <0.05). Besides, the expression of Skp2had a negative correlation with that of Cx43. Conclusion Skp2 and Cx43 may play an important role in the genesis and development of cervical carcinoma.

Objective To investigate the effect of different pharmacotherapy after lacrimal passage plastic laser operation. Methods Divided 90 patients (103 eyes) with nasolacrimal duct obstruction into group A (33 eyes), group B (36 eyes) and group C (34 eyes) randomly, each group consisted of 30 cases. Tetracycline cortisone ophthalmic ointment (TCO) was used to perfuse lacrimal duct in the end of the operation in group A, while TDO was used in group B and group C. In the first three postoperative irrigation, TDO was used only in group C, there are no no ointment during the course of irrigation in the other two groups. Followed-up survey for 3 months, evaluated the efficacy of the treatment in 3 groups. Results The therapeutic efficacy was significant better in group B than in group A (P

Objective To assess the change of plasma adrenomedullin(ADM)and endothelin(ET)in patients with essential hypertensin. Methods Concentrations of plasma ADM and ET were measured in 18 healthy control subjects and 52 patients with essential hypertension, 36 patients of which had no target organ damage, while 16 patients of which were complicated with renal impair. Results The concentrations of ADM and ET were significantly higher in patients with renal impair than in patients without organ damage. Plasma concentrations of ADM and ET were strongly positively correlated with blood urea nitrogen levels and serum creatinine levels. A strong inverse correlation between GFR and plasma concentrations of ADM and ET was found. Conclusion The increase of plasma ET and ADM may have an intimate relation to the renal function. ADM and ET may play some important role in the pathophysiologic makeup of hypertension and hypertension with renal dysfunction. ADM may act against excessive vasoconstrictor ET increased in essential hypertension and may be part of a compensatory mechanism to offset further development of renal impair.

Objective To compare the effects of sedation induced with midazolam and propofol on blood pressure(BP), heart rate(HR) and heart rate variability (HRV) during operation on lower extremity preformed under continuous epidural anesthesia in patients with the type Ⅱ diabetes. Methods Forty patients with type Ⅱ diabetes scheduled for lower limb surgery were randomized to receive either midazolam (group M n - 20) for propofol (group P n = 20) for sedation during operation, all patients were classified as ASA physical status Ⅱ or Ⅲ . The patients were unpremeditated. Epidural catheter was inserted at L2-3 or L3-4 . The local anesthetic used was 2% lidocaine. MAP,HR,HRV and SpO2 were monitored during anesthesia and operation. After onset of epidural analgesia a loading dose of midazolam(0.03 mg?kg-1 ) or propofol (0.7 mg?kg-1 ) was given i.v. followed by intermittent i.v. boluses of 1 /4-1 /2 loading dose to maintain the depth of sedation at OAA/S score of 3 (respond to name outer if called repeatedly) . Changes in HRV before and during sedation were recorded and compared between the two groups. Results The demographic data including sex, age and body weight were comparable between the two groups. LF and TP decreased significantly during sedation as compared with baseline in both groups ( P
